Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1450, here are decompositions:

3 + 1447 = 1450
11 + 1439 = 1450
17 + 1433 = 1450
23 + 1427 = 1450
41 + 1409 = 1450
83 + 1367 = 1450
89 + 1361 = 1450
131 + 1319 = 1450

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1450 first appears in π at position 13,622 of the decimal expansion (the 13,622ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
